Overview
The ADUM2250ARWZ-RL is a digital isolator produced by Analog Devices Inc. This component is designed to provide reliable and high-speed isolation for I2C, SMBus, or PMBus interfaces. It features hot-swappable capabilities and is based on Analog Devices' iCoupler chip scale transformer technology, which offers superior performance, size, power consumption, and functional advantages compared to traditional optocouplers.
The ADUM2250ARWZ-RL supports bidirectional I2C communication with open-drain interfaces, eliminating the need to split I2C signals into separate transmit and receive signals. This makes it particularly suitable for applications requiring isolated I2C interfaces, such as in power supplies, networking, and Power over Ethernet (PoE) systems.
